s24alarms.com website review

15 files block the first paint until they finish downloading. Deferring or inlining them could save about 24.6 s.

About 3.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 18.9 s faster on a phone.

5 images could be 750 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.8 s faster on a phone.

29 files are served with short cache lifetimes, so returning visitors download them again (776 KiB).

200 KiB could be saved by minifying JavaScript.

Your mobile performance score is 49 (desktop: 46). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

About 109 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 760 ms faster on a phone.

7 long tasks block the main thread while loading, the longest for 634 ms. During a long task the page ignores taps.

Google Tag Manager costs a phone 280 ms of main-thread work and 330 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

6 third-party services load with your homepage (Google Tag Manager, Facebook and Google Fonts and others), adding 798 KiB and 499 ms of main-thread time.

Polyfills for old browsers add 43 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

5 KiB could be saved by minifying CSS.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The first text or image appears after 25.7 s on a phone. Good is under 1.8 s.

Your largest element takes 37.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Visually, the page fills in at 25.7 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 37.9 s. Good is under 3.8 s.

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 806 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 292 ms in total while the page loads. Good is under 200 ms.

18 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 70 ms to 79 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.8 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.4 MB in 44 requests on a phone: scripts 4.6 MB (9), images 1.5 MB (20) and fonts 182 KiB (3). Under 2 MB keeps phones on slow connections fast.

5 images (536 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

2 images are downloaded at several times the size a phone draws them, for example ADT_Icons_ADTMobileApp.png at 2,042 px wide, shown at 70 px. Resized copies would save about 237 KiB.

3 images further down the page (296 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.81 g of CO₂e: 217.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 16 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

1 visible link has no text or label, so screen readers cannot say where it goes.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 29 characters: “Secure24 Alarm Systems - Home”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 5 pages on s24alarms.com and 6 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://s24alarms.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://s24alarms.com/About-Us, https://s24alarms.com/Contact-Us, https://s24alarms.com/Partners and https://s24alarms.com/PrivacyPolicy have no meta description, so Google writes the search snippet from whatever text it finds.

https://s24alarms.com/PrivacyPolicy has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 4 pages linked from your homepage and read each the way a search engine does.

2 of 6 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 errors were logged to the browser console while the page loaded, for example “Cannot read properties of undefined (reading 'getWidth')”.

Large scripts ship without source maps.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 481 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Meta Pixel (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 4 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
